The present invention seeks to eliminate the problems associated with the prior art. In particular, the present invention proposes an adapter in the form of a module connectable either directly or by means of a standard cable to a computer and peripheral devices operating under different interface protocols. For purposes of this application, the term "standard cable" will be used to refer to a cable having connectors at its ends that are related to a single interface protocol, and wherein the cable performs no protocol conversion. This is to be distinguished from a dedicated cable known in the art in which the cable is provided with different connectors at its ends, each connector being associated with a different protocol, and the cable having an ASIC chip for performing a protocol conversion.
A specific embodiment is described in which an adapter module in accordance with the invention is connected directly to an optical disk drive and connected by means of a standard cable to a lap top computer. The adapter module is further provided with a number of other parts or connectors for connecting further peripheral devices to the computer. It will, however, be appreciated, that the invention is not limited to the connection of computers to memory devices such as read-only or read-and-write memory devices, including hard disk drives, optical disk drives, removable hard disk drives, tape drives, CD family drives like CDR, CDI, and CDE, jukeboxes, or ROM or RAM chip sets, etc. The present invention is equally applicable to other peripheral devices such as printers, modems, etc. Furthermore, the invention is not to be read as being limited to the specific electrical connectors and protocols discussed but applies equally to any other connector and protocol such as serial ports, parallel ports, RS232 ports, SCSI ports, wide SCSI ports, fast SCSI ports, Ethernet ports, 10 Base T ports, IPI ports, IDE ports, EIDE ports, TCPIP ports, coaxial cable ports, and wireless ports such as infrared or radio frequency connectors, to name but a few.
A specific embodiment is now described with reference to the accompanying drawings.
FIG. 1 shows an isometric view of an optical disk drive 10 and an adapter 12 in accordance with the invention. The adapter module 12 is typically connected by means of a standard cable (not shown) to a computer, and serves to convert from one interface protocol adopted by the computer to a second protocol adopted by the disk drive. The adapter module 12 is illustrated in greater detail in FIGS., 2-5. FIG. 2 shows a sectional side view of the adapter module 12. The one side 14, which in this example corresponds to the computer side and is show in detail in FIG. 3, includes a DB25 connector serving as a parallel port for connection to a parallel port of a computer. The side 14 further includes a SCSI 36 pin connector 18 and two micro SCSI connectors 20, 21. A DC jack 22 is also provided. It will be appreciated that this is merely an illustrative example and that the module 12 could have a different number and different types of connectors. The opposite side, which in this example, corresponds to the disk drive side 24 supports a 50 pin SCSI connector 26 which is illustrated more clearly in FIG. 4. It also supports a DC plug 28. Again, the invention is not limited to the type of connectors illustrated in this embodiment and could include different types of connectors and more or less than two connectors. Mounted within the housing of the adapter module 12 is a printed circuit board 32 that supports an ASIC chip 34 as illustrated in FIG. 6. The chip 34 is connected by means of bus lines (not shown) to edge connectors 36 for connection to various connectors on sides 14 and 24 of the module 12. The ASIC chip 34 serves to perform protocol conversions from one connector to another. Such ASIC chips are commonly known in the art and are readily available from companies such as Shuttle Technologies, Inc. The printed circuit board also supports a temporary storage means 35. The temporary storage means can consist of a number of RAM chips, which serve as a buffer for information sent to the module 12 via the various connectors or ports. It will be appreciated that a buffer or cache could equally well be connected externally instead of being mounted on the PC board.
Referring again to FIG. 1 and to FIG. 7, the disk drive 10 is provided with a 50 pin SCSI connector 40 (as illustrated in FIG. 7) for complimentarily engaging the connector 26 of the adapter module 12. The side 38 of the drive 10 further includes a DC socket 42 for receiving the DC plug 28 of the adapter module 12. The disk drive 10 also includes a slidable cover 43 (FIG. 1) providing access to dip switches and SCSI identification switches (not shown). Furthermore, the drive 10 includes slidably mounted legs 44 to support the disk drive more securely on its edge. Another feature included to enhance the compactness of the system as a whole is the provision of rails 46 for slidably receiving portable storage media such as optical disks or cassettes. This allows extra disks or cassettes to be secured to the body of the drive 10. Clearly, the invention is not limited to rails. Any suitable attachment means, for example clips, could be provided on the drive 10, or on the adapter module 12.
In practice, the adapter module is simply connected to the end 38 of the drive 10 and is held in place by virtue of the connector 26, which engages the connector 40. Resilient retaining hooks 48 on the module 12 (FIG. 1) engage complementary recesses 50 (FIG. 7) in the end 38 of the drive 10 to securely mount the adapter module 12 on the device 10. The module 12 is, in turn, connected either directly to the computer, such as a lap top computer, or by means of a standard connector cable extending from the parallel port of the computer to the DB 25 connector 16 of the module 12. It will be appreciated that the connectors 18, 20, 21 can be connected to other peripheral devices thereby allowing the computer to communicate with such other devices. In another embodiment a further 50 pin SCSI connector can be provided for connecting another identical optical disk drive to the adapter module. Thus by providing 3 or more connectors on the adapter module 12, several peripheral devices can be connected to a computer and several memory devices could, for example, be daisy chained together.
As mentioned above, a wide range of connectors could be provided on the adapter module with appropriate printed circuit boards and appropriate ASIC chips being provided for converting from one protocol to another. The adapter module could, for example, support SCSI, wide SCSI, fast SCSI RS232, serial, parallel, Ethernet, 10 Base T, IPI, IDE, EIDE, TCPIP, coaxial cable or wireless connectors such as radio frequency or infrared connectors. Furthermore, a variety of devices could be connected to a computer or daisy chained together. For example, memory devices including read-only and read-and-write memory devices, such as ROM or RAM chip sets, jukeboxes, hard disk drives, optical disk drives, removable hard disk drives, tape drives, CD family drives such as CDR, CDI, and CDE, etc. and other devices such as printers or modems, to name a few, could be connected to a computer or to each other.
